Aluminum tolerance of maize cultivars as assessed by callose
production and root elongation.
content was determined by using a JASCO Spectrofluorometer FP-777 (Japan Spectroscopic Co, Ltd, Tokyo) with excitation at 350 nm and emission at 500 nm.
staining indicates numerous cytoplasmic connections between bundle sheath cell prolongations and neighboring non-vascular cells.
Using immunofluorescence and immunogold electron microscopy techniques, we characterized the distribution of various cell wall polysaccharides namely, callose
, cellulose, and pectins.
The developmental events after callose
By October, Cummings Carson said, callose
tissue should have formed around some canker margins if the introduced hypovirulent strain is reproducing.
2A), and a thick callose
wall surrounded the microspore tetrad (Fig.
After the dissolution of the callose
wall, the sporopollenin wall begins to form.
The sporocyte wall, usually consisting of callose
or mucopolysaccharides, isolates cells programmed to enter the meiotic pathway from the influence of surrounding vegetative cells.
Sucrose utilization via invertase and sucrose synthase with respect to accumulation of cellulose and callose
